Ouvrage Immerhof

Ouvrage Immerhof, also known as Ouvrage Ferme-Immerhof, is one of the largest petit ouvrages of the Maginot Line of north-east, France. Located near the community of Hettange-Grande, it is 7 km north of Thionville between the gros ouvrages of Molvange and Soetrich, the closest ouvrage to the Luxembourg frontier. It was part of the Fortified Sector of Thionville, in the Fortified Region of Metz, the strongest portion of the Line. Apart from its function as a communication post between the neighbouring gros ouvrages, Immerhof also controlled the road and railway routes from Luxembourg, which pass in the immediate vicinity. In addition, Immerhof protected other Maginot works in the vicinity: the casemates of Kanfen, the infantry shelter of Stressling, the observation point and shelter of Hettange-Grande, and a number of nearby blockhouses constructed during the Phoney War.
